Re: General design questions for EL84 amps
Steve, thanks for the circuit.  
 
The 12AU7 has a lower plate resistance yet than the 12AT7, (7K ish vrs 11K ish) so it's a worse match in a socket with a plate load for a 12AX7.  
 
The 12AU7 has a more distorted sound IMO than the 12AT7, by a perceptble amount. Maybe that accounts for the preference.  
 
I really like the AT for PI, but I don"t like the 12AX7 as a PI , either, so I like less (different) distortion than some.  
Dan
